This is intentional from the Nautilus crew:

I'll chime in because I agree it's a bit gratuitously different and likely to confuse users who have managed to get familiar with browser tabs.

It would seem most obvious to put the tabs above the path widget, so that the path widget is a component of each tab (the "Chrome" approach, you could call it). That would make the path 'bounce' visually when going from a view with no tabs to tabs, but I doubt it would be that bothersome.

[And if this attracts attention, I think an even more pressing papercut is that, tabs or panes or spatial, it's still quite hard to distinguish between "/extremely/long/path/to/something" and "/media/mountpoint/extremely/long/path/to/something" in the common case of working with copies. Assigning a subtly different background color to removable devices by default would be one quick fix.]
